i'm having a slight problem with my car at the moment, i have a 2004 04 ST170, when i go to start the car the battery light sometimes stays on and the cd player will reregister itself. i'm not to sure if the alternator or another part. if it is the alternator i'v found two, 80 amps or 100 amps, which would best suit the car?

cheers for your help

use a multimeter to test if the Alternator is charging. No charge. new alternator. Could be a tired battery as a tired battery can do funny things (reset radio) as cranking can take too much friom the system etc etc.
